5amp round 2pin sockets

553.1.2 Except for SELV or a special circuit from Regulation 553.1.5, every plug and socket-outlet shall be of the non-reversible type, with provision for the connection of a protective conductor.

553.1.4 Every socket-outlet for household and similar use shall be of the shuttered type and, for a.c. installation, shall preferably be of a type complying with BS 1363.

553.1.5 A plug and socket-outlet not complying with BS 1363, BS 546, BS 196 or BS EN 60309-2, may be used in single-phase a.c. or two-wire d.c. circuits operating at a nominal voltage not exceeding 250 volts for:

( i ) the connection of an electric clock, provided that the plug and socket-outlet are designed specifically for that purpose, and that each plug incorporates a fuse of rating not exceeding 3 amperes complying with BS 646 or BS 1362 as appropriate

( ii ) the connection of an electric shaver, provided that the socket-outlet is either incorporated in a shaver supply unit complying with BS EN 61558-2-5 or, in a room other than a bathroom, is a type complying with BS 4573

( iii ) a circuit having special characteristics such that danger would otherwise arise or it is necessary to distinguish the function of that circuit.

412 PROTECTIVE MEASURE: DOUBLE OR REINFORCED INSULATION.

412.1.3 Where this protective measure is to be used as the sole protective measure ( i.e. where a whole installation or circuit is intended to consist entirely of equipment with double insulation or reinforced insulation ), it shall be verified that the installation or circuit concerned will be under the effective supervision in normal use so that no change is made that would impair the effectiveness of the protective measure. This protective measure shall not therefore be applied to any circuit that includes a socket-outlet, luminair supporting coupler (LSC), device for connecting a luminair (DCL) or cable coupler, or where a user may change items of equipment without authorization.
 
You'd have to wire your house to the regulations applicable in those contries though wouldn't you?

No. There's nothing in the building regs. which says you have to wire to one, or indeed any, particular standard.
 
If you did not comply with a standard how would you know that you had made reasonable provision in the design and installation of the installation in order to protect persons operating, maintaining or altering it from fire or injury?

Do you not think that the requirement to protect anybody maintaining it or altering it would mean that you would have to document the standards or conventions you had adopted if they were not what would reasonably be expected in the UK?

Do you think that providing unearthed non-polarised and unshuttered socket outlets would be reasonably safe for people using the installation?

I see that we have varying opinions. I have some three pin ones somewhere I shall use thouse. I shall save the sockets for projects not involving mains :D

Not an uncommon occurrence around here! ;)

What's so special about having to comply with one particular standard throughout? Yes, there are issues with mixing standards; Shucko sockets on a 30A ring are bad for obvious reasons, but that's not the same thing as saying that Shucko and BS1363 can't coexist in the same building.

Do you not think that the requirement to protect anybody maintaining it or altering it would mean that you would have to document the standards or conventions you had adopted if they were not what would reasonably be expected in the UK?

Would it be unreasonable to expect 2-pin 5A BS sockets in the U.K., given that there are still installations from the 1950's out there with them? But wasn't P2 removed from the building regulations anyway?

Do you think that providing unearthed non-polarised and unshuttered socket outlets would be reasonably safe for people using the installation?

Yes, if used properly. How would they be any less safe than the unearthed, non-polarized, and non-shuttered sockets which are still in the standards of some EU countries?

Have you typed the whole book out
 
Between us, probably yes, and then we keep links to the regulations which we quote often so they can be copied and pasted in.
 
I assume he just scanned it and ran it through Finereader.

Because the more you mix and match, and the more you don't adhere to any standard but just do things which you think should be OK, the less reasonable your actions become.

Not newly installed, no.

Do you think that choosing not to work to the most obvious standard to use in this country purely because you've got a box full of old sockets that no longer comply with the standard, and you want to use them just to save a few quid, would count as reasonable?


But wasn't P2 removed from the building regulations anyway?
It was, but what's that got to do with it?

Because they would not be reasonably to be expected in this country.

If, say, somebody wanted a few Shucko sockets around a room for some reason, why do you think it would be unreasonable to run a circuit or two for those outlets in an installation which in other respects is to BS7671?

How would those sockets and the associated circuits be any different from the same sockets and circuits if the entire house had been wired to VDE or some other standard?

Do you think that choosing not to work to the most obvious standard to use in this country purely because you've got a box full of old sockets that no longer comply with the standard, and you want to use them just to save a few quid, would count as reasonable?

If there's a good reason for wanting to deviate from the "obvious" standard, or in fact for wanting to work to some other standard entirely, then yes, it's reasonable.

The government guidance on compliance with Part P doesn't in any way state that failure to comply with the "obvious" standard would result in non-compliance with the requirement for "reasonable provision for safety."

But wasn't P2 removed from the building regulations anyway?
It was, but what's that got to do with it?

You asked about documenting standards or conventions if they were not ones reasonably expected to be used in this country, in order to satisfy the requirement for anyone maintaining or altering the installation in the future. As P2 was revoked, no such requirement now exists.

How would they be any less safe than the unearthed, non-polarized, and non-shuttered sockets which are still in the standards of some EU countries?
Because they would not be reasonably to be expected in this country.

But how does that make them any less safe?
 
unearthed - obvious danger from a fault if the item being plugged in is not DI..
unshuttered - they're kicking up a fuss over socket blanks that let toddlers stick a straightened paperclip down the tiny hole left.. so a great big gaping hole is an even bigger target..
non-polarised - leaves the live connected when switched off on items with single pole switches and if the plug is reversed..
